This design is of Lavernius Tucker, often considered the main character in the Chorus Trilogy because of the part he plays. He, like the other reds and blues, is fairly ignorant and funny, making him popular with the community. Like the other reds and blues, he is also unskilled in combat. At the end of season 13 he takes the experimental suit built on the Meta's by Charon Industries and makes a last stand with the other reds and blues against the pirates.
